3.4. Effect of fish powder, frying temperature and frying time on hardness
There was a significant difference (P < 0.05) in hardness among the fried rice crackers with fish powder content of 0, 5, 10 and 15 g/ 100 g (Fig. 1c).
Hardness of fried rice crackers mixed with fish powder content of 15 g/100 g gradually increased with increase in frying temperature and frying time (Fig. 2a).
There was also a significant difference (P < 0.05) in hardness between the rice crackers fried at 200 and 240 C.
hese results are in agreement with literature discussing that higher frying temperatures and times enhance crust formation
